Fipronil is an effective insecticide widely used in agriculture with potential ecotoxicological consequences. The median lethal dose (LD50) and concentration (LC50) of fipronil in 16.3 g Caspian white fish, Rutilus frisii kutum fingerlings were determined. To determine the LD50, a total of 133 fish were assigned to 19 tanks (7 fish/tank) including one control and 6 treatment groups (300, 450, 5...

BACKGROUND AND OBJECTIVES The US Environmental Protection Agency has suggested faecal enterococci as the primary bacterial indicators. Of more importance is their direct correlation with swimmer-associated gastroenteritis in recreation water quality monitoring. In contrast to other seawater bodies with 3.5% salinity, the recreational waters in the southern coast of the Caspian Sea possess its o...

Amphipod fauna of Moldova remains one of the least known in Europe with the most recent data upon species distribution being already almost 50 years old. In this paper, we summarize the knowledge upon the distribution of amphipods in Moldovan inland waters based on literature survey combined with our new original data and present a comprehensive checklist of recorded amphipod species. The new o...

INTRODUCTION Our aim was to compare changes of body mass index (BMI) and waist circumference (WC) curves of Iranian children by comparing the results of two national surveys of a surveillance program, i.e. CASPIAN-I (2003-2004) and CASPIAN-III (2009-2010). The second objective was to evaluate the prevalence of obesity, overweight and underweight among 10-18-year-old Iranian children and adolesc...

Problem statement: Uterine cervix which separates the uterus from the vagina, shows remarkable anatomical and histological differences among mammalian species. Since no cleared observations have been found in regards with the Caspian miniature horses’ cervix, the aim of the present study was to supplement this missing information which could be helpful for providing a stricter basis in detectin...
